These preliminary results strongly suggest the great potential of this novel electron transfer material in high-efficiency perovskite solar cells. Meanwhile, the uniform core-shell 2 nanoparticles is extremely favorable to the growth of inorganic perovskite films. A homogeneous precipitation method has been used to synthesize SnO 2 NSAs, following by atomic layer deposition of ZnO. The core-shell 2 nanoparticles size is 8.1 nm with the SnO 2 shell thickness of 3.4 nm, and the electron mobility is seven times more than SnO 2 nanoparticles. In this letter, well-defined SnO 2 /ZnO core-shell nanosheet arrays (NSAs) are grown with an on-chip two-step process as gas sensing materials. The relationship between the gas sensing properties and the electrical properties and crystalline phase are discussed. SnO2:F transparent conductive thin films with the area of 500×500mm2 were deposited on glass substrates by spray pyrolysis using SnCl45H2O and HF as the. Thanks to the good match between the energy level of the SnO 2 shell and the high electron mobility of the core ZnO nanoparticles, the PCE of inorganic perovskite solar cells has reached 14.35% ( J SC: 16.45 mA cm -2, V OC: 1.11 V, FF: 79%), acting core-shell 2 nanoparticles as the electron transfer layer. Chapter 4 describes the investigation of 2D structured thin films of ZnO and SnOx deposited by rf/dc sputtering and the effects of processing parameters on the electrical properties and preferred crystalline phase of the materials. In the presence of air, stannous oxide burns to form the dioxide, or stannic oxide, SnO2, a white insoluble solid.
Here, a novel electron transport material was designed and synthesized by using a simple and facile solvothermal method, which is composed of the core-shell 2 nanoparticles.
The ideal charge transport materials should exhibit a proper energy level, high carrier mobility, sufficient conductivity, and excellent charge extraction ability. 5H 2O and NaOH were continuously stirred in DI water for 1 h for Zn2 SnO 4 microcubes synthesis.
